On'the left hand side, the` resilient arm v2l) `ofspring metal vis provided with a1downwardlycurved plate bearing `end 2| l arrangedto seat infattralnsverse slot or recess 35 22,1in theplate end `I4,and at its opposite end is providedwith arailengagingportion 23. `The part 23 1exerts pressure, in ahorizontal direction, against the' rail basefiange edge IB. u Just above the part 23 is a rail-overhanglng member 2,3' 40 which is an integral part o1' the arm 20. The. arm 2li` is apertured between its ends` and a screw bolt 24 is adapted `to extend upwardly through said aperture. Thehead 25 of the bolt 24 is adapted to entera recess 26 formed in the `i5 and partially close said recess 23. The resilient arm 20 is placed over thebolt 24 and moved downwardly into the position shown in the drawings, and is held under tension by a nut 2l screwed down on the bolt 24.

The shoulder I2 is cut away to accommodate the arm 20 between the shoulder ends 29. When the parts have been assembled into .the positions shown, and the arm 20 is under tension, the rail engaging end 23 bears on the outer face I3 of the' rail base ilange, and retards or eliminates creeping of the rail. The overhanging member 23 retards vertical movement of the rail but the rail and plate connection is non-rigid and, therefore, the wave motion oi.' the rail does not lift the rigidly connected plate and tie from the roadv bed.

Referring now to the form of connecting means shown at the right hand side of Figs. 1 and 2, the resilient arm 30 has its plate bearing end 3| seated on the plate end I5, against a transverse shoulder 32. Its opposite end is split, forming a pair of rail engaging ends 33, and a rail-overhanging member 34 between the ends 33. The recess 25 and the arm fastening bolt and nut 24 and 23 are identical with similarly designated parts heretofore described.

` Referring to Figs. 4 and 5, for purposes of il-` lustration two forms of rail and plate connecting means are shown on one tie plate. At vthe left, the resilient arm 35 has a plate bearing end 35 seated on the plate end I4, against a shoulder 31. At its opposite end the arm forms a rail bearing member 33, terminating in a rail-overhanging end 39. The arm 35 is apertured and a screw spike 40 extends through said arm aperture and a hole in. the plateend I4, into the tie 4I, holding the resilient arm down on the plate, under tension, and also fastening the plate to the tie.

At the right hand side of the Figures 4 and 5 the arm 42 has its plate bearing end 43r shaped to straddle the screw spike 40, and at its opposite end terminates in a rail bearingmember 44. In this form I preferably use a clip 45 between the head of the screwspike 40 and the arm 42. The clip is rectangular, as shown, and bears against the plate and shoulder 45 at its outer edge and on the arm 42 at its inner edge.

At the left hand side of Figs. 6 and 7 the re silient arm 41 has a plate bearing end 43, seated against the shoulder 49, and on the opposite end the arm 41 is split, forming a pair, of upturned, rail bearing surfaces 50, terminating in railoverhanging ends 5i. Between the two members 50-5I is a downturned member 52 extending into a punched slot 53 in the plate I0, with the end of the part 52 beneath the edge oi the rail base flange. The arm 41 is held on the Plate and under tension by the screw spike or bolt 40 heretofore described.

At the right hand side of Figs. 6 and 7 the resilient arm 54 has its plate bearing end 55 shaped to straiddle the screw spike 40, and at its opposite end is bent toform aL rail-overhanging member 55, and then bent downwardly to provide a rail ange bearing member 51 terminating in an end 58 located in a punched out slot 59 in the plate I0. The resilient arm is held under tension on the plate by the screw spike 40.

'Ihe tie plate may be f ormed in a U or L section, transversely; that is, with one or two depending flanges which have bearings against both sides -or one side of the tie, thus reducing the strain on the connection between the tie plate and the tie caused by the tendency of the rail under traillc to creep.

The form of fastening device 24, 25, 28, shown in Figs. 1-3 may be substituted for the devicesi 40-45 of Figs. 4-7, inclusive, and vice versa.

Each of the spring metal arms 30 and 42, is provided with a rail engaging portion so located and formed as to normally exert non-slipping or biting bearing pressure in a horizontal direction only against a vertically disposed face of the rail base ange when the arm is under tension; such tension being produced by the engagement of the plate bearing end oi.' the arm with a rigid part of the plate and of the downward pressure of a clip, screw spike, bolt, or the like for fastening the resilient arm to the plate. Thus the tie and plate maybe rigidly connected together by screw spikes or bolts, and such connection will not be disturbed by the wave motion of the rail, non-rigidly held on the plate.

The tie plate may be provided with means for temporarily establishing a rigid connection between the plate and rail as described in Willard United States Letters Patent No. 1,854,497.

Changes may be made in details of construction without departing from' the scope of' my invention and Ido not intend to be limited to the exact form shown and' described, except as set forth in the appended claims.
